GAS-WASHER TOWER.

Application filed July 15,

To (ll/b wnom it may concern Be it known that I, WVALTHER MATHEsIUs, acitizen of the United States. residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Gas-Washer Towers, of which the following is a specification. I

My invention relates to battles for use in a gas washer tower,particularly the upper portion thereof, and has for its particularobject thereinoval of the finer particles of dust and dirt from the gasas it passes through the gas washer towerby varying the flow of the gastherethrough and changing the direction of the current of the gas. Itwill be understood that in building gas washers it is the practice toprovide spaced hurdles in the lower portion of the gas washer towerthrough which the gas passes and where it is brought into contact withstreams of water passing downward over the hurdles, which removes thecoarser particles of dust and dirt from the gas. After the gas haspassed through the? hurdles it passes upward through the gas washertower and through sets of baflics arranged in the upper portion thereof,which are adapted to catch the smaller particles of dust and dirt whichwere not removed at the time the gas passed through the hurdles.

It is the practice to insert these batlles in sets composed of one pairof frames. each of said frames heretofore being made up of bafilcplates'disposed at an angle with respect to the vertical plane of thewasher tower. all of the plates of each frame being turned in the samedirection and extending entirely across the washer tower. The baflleplates of one of the frames making up each set is turned at right anglesto the battles of the other frame making up the set, the bullies ot'both of the frames extendin; transversely across the washer tower inthe, same direction, The gas passing upward through the arrangement ofbattles in. this form is turned first toward one side of the washertower and thence to the other side of the towel as it passes througheach set of plates.

I have found in practice that a considerable improvement is attainedover the results heretofore accomplished by arranging the bafile platesof each frame in sections,

such sections constituting sectors of a circle 1920. Serial No: 396,550.

in their horizontal planes, the battle plates vertical direction oftravel alternately to- Ward the axis of the tower and then outwardlytowards the shell of the washing tower. Also the one sided working orthe channeling of the gas to one side of the tower is overcome and auniform distribution of the gas over the entire battle area is secured.Furthermore, I am able to place the spray nozzles in such position thatintimate contact between the water and the gas is secured and the spraythrown in a direction either the same as the travel of the gas. or in adirection exactly opposite to the travel of the gas. and thus secure auniform distribution of the water over the baillc plates.

I also provide a spray nozzle to direct a spray of water against eachsector of the frame, thus providing for a more even distribution of thewater used in the washing operation. This even distribution of the watercauses the washingdown and removal of the finer iarticlcs of dustand'dirt with much more thoroughness than has been possible to securehereto-Fore.

Another and further object of my invention is the provision of baillcplatesin such manner that the gas passing through the said tower isuniformly distributed as it passes through the baille plates and therebya more intimate contact can be made between lhe water and the gas as itpasses through the baliics, thus resulting in more ellicieut washing.

These and other objects of my invention will be apparent to thoseskilled in the art by reference to the accompanying drawings, in which:

Figure 1 is a view of agas washer tower partially in section through thebaflle plates and partially in elevation; and i Figure 2 is a plan viewof one of the trames/ showing the arrangement of the baffle plates.

'Referringnow specifically to the drawings, 10 is a gas washer towerhaving a gas ing held in'pOsitiOn' inlet pipe. 11 and ages outlet pipe12. In the upper portion of the gas washer tower I provide three sets ofballles. each set being made'up of a lower frame 13, and an upper frame14, r'espectively, the said fframes beby means ofangles 15, which aresecured-to the wall of the gas washer tower in any approved manner. A

; zles 17 may he turned downward sojthat a spray of water-is directedagainst the u pper' frame 14: of each set of ballles in the same manneras the "nozzles 18, although I have found in practice that thearrangement shown is preferable. I I

Referring specifically to Figure 2, wherein is shown one of the frames13,"a circular frame member 1935 provided having a pair offrame members20, 21 secured thereto at each of their ends, the said frame membersextending'across the circplar 'frame' 19 and crossing eachotherat' rightangles at the center of thefra'me' 19 and thereby dividing the-frame 19into'four equal sectors. Secured to the frame 19 and to the crossmembers 20 and 21 is a plurality of-baflle menibers 22, the said balllemembers being dispos ed'at a-n angle'with respect to the vcrtical axisof thengas washer tower. Filler blocks Qgare provided-between the framemember-Bland the outer one-oi. the baffle plates 221 Spacers 24 ,arealso provided. at the outer ends of the baffle plates 23 and ifnecessary, in order tosecureproper spacing, spacers 25imay be positionedintermediate the ends of the balilc members 22, although in practice Ifind that the spacers are only necessary between the longest of thehallle plates 22. it will thus be understood that the gas in passingupward through the gas washer tower comes in contact with the lower setof bafiles liland the llowbf gas is directed inward after passingthrough the. said set or" baffles 13,and is directed upward by means ofthe bullies 14stowards the gas washer tower wall. This .jporationisrepeated. with the passing of the gas through each setof inclinedbullies and: the dirt and dust is lodged against the baffles by beingimpinged against the said ballie plates. The spray nozzles di rect aflow of water in a direct line with the bellies and passes upwardbetween the ballie plates of each of the lower sections so that sectorsand also with respect to ssues they are kept constantly washed clean andthe nozzles 18 direct a spray of water downward into the topmost sectionof the upper row-of badies and in a direction exactly op posits to thatin which the gas is passing alter it leaves this bathe-section. It willbe thus understood that an even How of gas is maintained throughout theupper section of the gas washer tower and that the gas is evenlydistributed throughout said section seas to insure a. more thoroughcleansing and washing of the than has been the'practice heretofore.

' While I have'described more or less preci'sely the details ofconstruction, I do not ivish to be understood as limiting myselfthereto, asl contempl-ate changes in form and the proportion of partsand the substi: tutionj of equivalents as circumstances may suggest orrender expedient without departing from the spirit'or scope of myclaims.
